The extensive move to remove the Confederate Flag from public and some commercial settings has raised serious concerns over both free speech and academic freedom. While the flag has been used as a racist symbol, it is also a historical symbol. According to one author, that distinction appears to have been lost by Amazon, which reportedly took done the book by Michael Dreese, a civil war author with six books on the conflict. Two of those books concern both the Union and Confederate battle flags and their roles in the Civil War. However, “This Flag Never Goes Down” (a book on the Confederate flag) was taken down by Amazon from its listed works.
